Re: Handy Holley Tuning Tip
Used as a tuning check tool, extremely marginal info/feedback input, done the right way in setting the correct fuel liquid level, absolutely essential to doing it right.
And, it isn't the fuel volume weight that is in play, but the change in the amount of fuel pulled in for the vacuum level pull. At the same vacuum, lower liquid level, harder vacuum pull, higher, easier fuel pull, but, that is what the jets, fixed air bleeds and air correctors are for. Plus, too high can lead to fuel dribble into jet passages, richness and just plain rotten engine running.
This is a lot like soe sizes for one set dimension foot, too big, problems, too small, problems, and PAIN.
As far as carb angle being effected by vehicle attitude, none of you guys ever hear of a carburetor wedge for a BOAT?
